Reverse-link power control strategies for CDMA cellular network

Power control (PC) is an important issue in the DS-CDMA cellular mobile radio system. For the IS-95 standard, the reverse-link PC strategy is based on fixed-step power change and it needs only one command bit per update. We call this strategy DM-PC. From the point of view of digital communication, ADM will have better performance with the same number of control bits compared to DM. So it appears to be a good idea to improve the DM-PC and be compatible with the current system as IS-95. However, the pure ADM-PC is not better than DM-PC from our earlier simulation results. Hence, we propose another PC strategy called modified ADM-PC. The simulation results show that it has better performance than DM-PC.
